摘　　要：当前电力系统中,以人工为主的运行维护方式已无法满足线路运维的需求。为了解决以上问题,采用激光扫描三维成像技术,通过激光的发射与接收并利用全球定位系统以及惯性导航系统,可快速获取被检测对象的空间数据。结合国内外最新研究进展,将激光扫描仪、POS系统、高清相机等设备研发集成为一套机载激光扫描采集系统,获取了输电线路及线路走廊内三维激光点云、影像等数据,实现了各类数据采集的同步性、工作平台的一体性。利用获取的三维数据对线路走廊开展了三维量测、危险点智能检测分析与预警,成功应用于华北500kV昌门线路运行维护。结果表明,利用直升机搭载激光扫描三维成像系统,能够帮助电网运维部门在最短时间内收集输电线路走廊及设备本体三维信息,为输电线路运行情况评估、故障分析诊断、应急抢险方案制定等工作提供了技术支撑。In the power system,the traditional ways of artificial maintenance of the line can not meet the acquirements of power system.In order to solve the above problem,light detection and ranging（LIDAR） technology can be used to get spatial data of objects quickly.Through the laser transmitter and receiver,with the data from GPS and inertial navigation system（IMU）,the helicopter LIDAR technology can help the operational management department of power system to acquire transmission line corridors and equipment＇s 3D information.According to recent research at home and abroad,a set of three-dimensional laser scanning imaging system has been integrated including scanner header,IMU and digital camera.The 3D data has been successfully used in the operation and maintenance of transmission lines.The results show that the adoption of helicopters LIDAR technology can provide a technical support to the transmission lines in operation assessment,fault analysis and emergency rescue.
